[Bug 1555562] Re: lastpass-cli changed bundled CA certificates

2018-06-13 Thread Nikolay Turpitko via ubuntu-bugs
Hi Robie and others,

Sorry guys, since I reported this bug 2 years ago, I gradually switched
to Debian system and pass/gopass password manager (even deleted lastpass
account). So, currently I don't use neither Ubuntu nor lastpass daily
(not because they are any bad, but due personal preferences). For
testing new package I'll need couple hours of spare time, which I don't
have right now. So, don't wait me, someone else please take an action.

[Bug 1758389] Re: List of partitions for overlayroot

2018-03-26 Thread Nikolay Turpitko via ubuntu-bugs
Please disregard last paragraph in my comment #1. I've found that I was
not able to boot with recurse=1 not due of read-only /var, but due of
script's attempt to remount absent cdrom for which I have an entry in my
/etc/fstab (added by system installer).

Nevertheless, I found new configuration useful to exclude some filesystems from 
recurse. For example, to properly boot with (separate) read-only /,/boot,/var 
and read-write /home I use string like below in my /etc/overlayroot.local.conf:
overlayroot="tmpfs:swap=1,debug=1,driver=overlay,recurse=not:cdrom|home".

I checked - this syntax also works for kernel command line, I only had
to put recurse option in single quotes like: "...
overlayroot=tmpfs:swap=1,recurse='not:cdrom|home'".

Simplified conditional logic and allowed to negate expression.

[Bug 1758389] Re: List of partitions for overlayroot

2018-03-24 Thread Nikolay Turpitko via ubuntu-bugs
I attached a patch, illustrating changes I propose.
I amended "recurse" option so that it take a regexp of filesystem names to work 
on, besides old values "0" and "1". That is, old values keep their meaning, but 
if recurese is set to something like "boot|backup" it will work only on those 
filesystems.

I tested with option
`overlayroot="tmpfs:swap=1,recurse=boot|backup,driver=overlay"`. It
works for me, but I don't know other use cases, for which people use
this package and cannot properly test them, obviously. Also, reusing
"recurse" option though simple, but may be questionable by someone. So,
see the patch as an illustration of idea, not as a completed solution.

Also, I found that "overlayroot-chroot" did not mount separate /var
partition and without it apt/dpkg failed to properly remove packages. I
added "var" into list of filesystems which "overlayroot-chroot" binds
before executing chroot. This is also may be not inline with original
design, but I just don't know how to properly deal with it.

With these modifications package works for me, but still is not quite
perfect solution for my goal. Which is to protect /, /boot and /backup
partitions of my laptop from incidental modifications, but leave /home,
/var, /swap and /tmp partitions in rw mode. I do not want to mount all
partitions as a single /, because I have SDD+HDD and partitions should
be on different drives (for example, / is on SDD and /var - on HDD).
Also I do not want to mount my /home as ro. And in my tests I even was
not able to boot with read-only /var. With my modifications and settings
I can boot and work with system almost normally, except that incidental
attempt to remove package without "overlay-chroot" can modify dpkg's
database (which is on rw /var), though / and /boot are protected and
restored after reboot alright. Alas, it leaves system in a half-damaged
state. I'd appreciate some idea to prevent this. But, probably, just an
alias will do.

[Bug 1758389] [NEW] List of partitions for overlayroot

2018-03-23 Thread Nikolay Turpitko via ubuntu-bugs
Public bug reported:

I'm experimenting with overlayroot in VirtualBox.
In my setup I have separate /boot, /var, /home and / (root) partitions.
I want /boot and / (root) partitions be protected with overlayroot=tmpfs, but 
others be mounted normally as rw. There is an option 'recurse', but it allows 
only to switch on/off handling of all other partitions, which is not suits my 
needs.

Is it possible to add another option like
'overlayroot_partitions=boot,backup' or
'overlayroot_exclude_partitions=home,var'?

** Affects: cloud-initramfs-tools (Ubuntu)
