Public bug reported:
zram-config, even after uninstalled, leaves behind the /etc/init/zram-
config.conf file, likely because it's marked as a conffile
This file, being the only actual functional file in zram-config, and the
only thing needed by Upstart to configure zram swaps, doesn't check
whether the zram-config package is installed before merrily continuing
as if zram-config were actually in the system.
I suggest to move some of the /etc/init/zram-config.conf code into shell
scripts that are tested for presence (or executability) before being
run, exiting silently if they're not there.
If they're absent, this means package is uninstalled and zram-config
should exit silently.
It'd be nice if, in the process, some configuration moved into
/etc/default/zram-config, like the fraction of the ram that should be
used for zram swap (in the line around "(1/2 of ram)" comment in "zram-
config.conf").
Steps to reproduce:
$ sudo apt-get install zram-config
$ cat /proc/swaps
(see zram swap(s))
$ sudo apt-get remove zram-config
$ sudo reboot
(wait for reboot and open terminal again)
$ cat /proc/swaps
(see zram swap(s) still there when they shouldn't)
The workaround is to type
dpkg --purge zram-config
Which finally removes the upstart script and stops zram swaps from being
configured at boot.
