Also, as for a bootable flash drive, if you use logical volumes for mount partitions, it works like a charm. If not, depending on the other physical drives, during boot, drive letters may change (I believe during the initramfs part of the boot).
It was basically like this: - install a bare bones Gentoo system on a hard drive in the usual way, and make it do whatever you'll want when it goes to the pen drive. - build the kernel with several modules built in, in special usb storage (of course) and all related to LVM (Gentoo Wiki is great!), and also, as I use "genkernel", there is a command line argument "--lvm" - create a few partitions on the pen drive (on mine there are two, but one is enough), create logical volumes for /boot and / - or /root - at least) - using grub2, in the file /etc/default/grub, the kernel command line should include "dolvm scandelay=10 rootdelay=10" (the numerical values are far from optimized). - mount the root partition in another directory (so that other mounts would not appear), copy it to yet another directory, strip it down (since I use squashfs and it is read-only, there is no reason to have /usr/src , /usr/include , /usr/portage and many others), then copy to the pen drive root partition; special care should be taken with /etc/fstab . - umount your current /boot partition, mount the pen drive boot partition in /boot (just to make things look familiar), mount the hard drive boot partition elsewhere, copy its contents to the pen drive boot partition, and issue a grub-install to the pen drive disk (/dev/sdb, for instance) and grub-mkconfig -o /boot/grub/grub.cfg That's very incomplete, since, for instance and as already mentioned, I use a squashfs root partition, so I had to figure out some ways, using unionfs, to have a writable partition mounted on top of the read only one for /var and for /etc (at least). 2014-03-28 12:00 GMT-03:00 Francisco Ares <fra...@gmail.com>: > To auto log-in, I use a feature of "agetty": > > On /etc/inittab: > > # TERMINALS > # c1:12345:respawn:/usr/bin/fbi -a -noverbose --nocomments > /etc/splash/natural_altec/images/silent-1024x768.jpg > c1:12345:respawn:/sbin/agetty --noclear 38400 tty1 linux > c2:2345:respawn:/sbin/agetty 38400 tty2 linux > c3:2345:respawn:/sbin/agetty 38400 tty3 linux > c4:2345:respawn:/sbin/agetty 38400 tty4 linux > c5:2345:respawn:/sbin/agetty 38400 tty5 linux > c6:2345:respawn:/sbin/agetty -a AutoLogInUserName 38400 tty6 linux > > And for auto run, after auto log-in accomplished, I use ".bash_profile" on > the auto logged-in user's home directory. > > Hope this helps > Francisco > > > 2014-03-28 11:15 GMT-03:00 Peter Humphrey <pe...@prh.myzen.co.uk>: > > On Saturday 22 Mar 2014 19:37:35 Neil Bothwick wrote: >> > On Sat, 22 Mar 2014 13:57:22 +0000, Peter Humphrey wrote: >> > > I've installed that old favourite SysRescCD on a pen drive, following >> a >> > > method I found on the Web to include a persistent file-system with all >> > > the extras I wanted in, e.g., /usr/local/bin. >> > > >> > > It works well, except that I haven't found yet where to put all my >> > > aliases to have them sourced at (auto) log-in. >> > >> > There is a file that is executed by default at login, I think it >> > is .autorun.
