After that point nothing's going to work because your new root filesystem (/target/) is faulty, and is now read-only, so there's no way to create the /target/boot directory, so the mount of the boot partition fails. My guess would be an underlying hardware fault on whatever /dev/sda2 is. I don't suppose there's any chance it's a fake USB stick - see: http://oss.digirati.com.br/f3/ (packaged for Debian as ``f3'') Cheers, Phil. -- |)| Philip Hands [+44 (0)20 8530 9560] HANDS.COM Ltd. |-| http://www.hands.com/http://ftp.uk.debian.org/ |(| Hugo-Klemm-Strasse 34, 21075 Hamburg,GERMANY signature.asc Description: PGP signature

all four of those functions are available via the apt command these days.

That's OK if you happen to have gone to the effort of learning what you
need to type to get what you want done, but even then you still need to
put some effort into keeping up to date if you want to get hold of new
features.
For instance, I know there's a better search thing for finding packages
than 'apt search ...' because I've seen it done, but I can never remember
it -- you get that sort of improvement for free if it gets added to
whatever UI you were using anyway.
Sadly, I don't have suggestions for better GUI apt-things, as I too
favour the CLI -- I'd guess that KDE has something competent.
There's 'goplay' for finding games and the like (it has other flavours,
such as 'gonet' for things tagged as networky rather than gamey, in the
package), but it's not general purpose, or featureful.
Cheers, Phil.

When wondering that sort of thing, I generally try this sort of command to find out: sudo find /sys /proc -name \*swappiness\* | less which in this case leads you quite quickly to /proc/sys/vm/swappiness which you can do things like: cat /proc/sys/vm/swappiness and echo 1 > /proc/sys/vm/swappiness with. Of course, that will only persist until the next reboot, so you'd then want to set things in /etc/sysctl.* to make things permanent. There are man pages for sysctl.d, sysctl.conf and sysctl, and also a README in /etc/sysctl.d/ Something like this (as root) would do the trick: echo vm.swappiness=1 > /etc/sysctl.d/local-swapiness.conf (that's all true on Debian -- no idea how much of that applies for *bian derivatives).

Presumably the system had a root password set at first install. That is what normally determines whether the first user created at install time is added to the sudo group or not -- having no root password provokes a user with sudo access, so that there is still some way of becoming root. If you're doing it by hand, just run this as root (assuming a user 'phil'): adduser phil sudo As for the question of remote root ssh access -- by default in the debian ssh package that is now only allowed using keys, rather than password, so you need to copy your .pub over to: /root/.ssh/authorized_keys on the target system to get in as root.

It seems that it's running su not sudo, and hence is expecting root's password, rather than your password. As someone who uses apt (or apt-get on older systems) running as root, I'm afraid I've no idea what might entice aptitude to choose su vs. sudo in this case, sorry. Running aptitude as root from the start is fine though.

That sounds like a reason to set up an additional repository, containing that kernels, and encouraging people to use it. Relying on a git pull strikes me as a (perhaps small) security risk in comparison. If someone wants to compromise such systems, they can set up a git repo with trojaned kernels, pull some DNS ticks, and get you to pull from them instead. If you instead set up a signed repo, then the signatures wouldn't match, so apt would refuse the upgrade. (reprepro makes setting up and maintaining such a repo pretty easy, and if that's overkill there are other alternatives available) If the problem is actually getting upgrades of the kernel that you were not wanting, then it is generally possible to specify the behaviour you want using "apt pinning" (see the apt_preferences(5) man page) Cheers, Phil. -- |)| Philip Hands [+44 (0)20 8530 9560] HANDS.COM Ltd. |-| http://www.hands.com/http://ftp.uk.debian.org/ |(| Hugo-Klemm-Strasse 34, 21075 Hamburg,GERMANY signature.asc Description: PGP signature

I've not really bothered with HAM stuff since I was playing with Packet Radio before dial-up Internet became a thing, but I find your claim that there's nothing much for Unix, suspicious: Long ago (early-mid 90s) part of what caused people to be interested in Debian was the prospect of a HAM specific version (which didn't quite happen, since Bruce Perens & Bdale Garbee got busy with Debian in general). More recently: https://www.gnuradio.org/ Also, the likes of this: https://events.ccc.de/2015/07/10/rad1o/ I know for instance that a decade or more ago Bdale was using SDR on Linux (or at least talking about someone he knew, in which case Bdale probably set it up) to record the whole amateur band in one go. All of which suggest that there's more than nothing going on in the world of *nix SDR.

2.2 CD images appearing
The 2.2 CD images are available from cdimage.debian.org. At present, I'm not happy about the alpha sparc images, so until the images get linked to the 2.2_rev0 directory tree treat them as pre-release still. The rest seemed to build fine though, and even if the alpha or sparc CDs change, they will be pretty close to what's there now, so rsyncing should be relatively quick. Remember to use the -H option to rsync to preserve the hard-links between the potato_test 2.2_rev0 images, otherwise you'll waste a load of bandwidth and disk space. The full CD mirror now takes a little over 14GB ALPHA Problems: tools/boot/potato/post-boot-alpha was not executable, so I'm rebuilding that now. SPARC Problems: I forgot that the sparc build needs to be done as root (or at least fakeroot) so it can create the device files it needs, so I'll be rebuilding that next. ARM Problems: There are no Release files --- does anyone care? If you're not actually running a mirror, please wait until this stuff starts appearing at mirrors, rather than going straight to cdimage.debian.org, otherwise it'll never get to the mirrors. If you are running a mirror, then please use the pseudo-image-kit if at all possible, and if it's not possible then use a mirror that has more bandwidth (like sunsite.org.uk for example, who already have the binary-i386-1 and 1_NONUS images available) If people could mention when they've got copies of the images, so that others can start mirroring from them, it might help spread the load more (cdimage.d.o is only a P166, so cannot stand too many rsyncs). If things get out of hand, I may switch the password checks back on until the excitement dies down, so if that happens, and you're running a top level mirror, and you've not got a password, mail me. Cheers, Phil.
