Package: initscripts
Version: 2.88dsf-13.4
Severity: wishlist
Hi,
I installed initscripts from experimental. All seems fine (and fairly
sane; thanks!), but I haven't rebooted and I'm a bit of afraid to
since there is no sign udev is fixed yet. So time to downgrade:
# cupt install initscripts/sid
Parsing Found/Fixed information... Done
dpkg: warning: downgrading initscripts from 2.88dsf-13.4 to 2.88dsf-13.2.
(Reading database ... 141278 files and directories currently installed.)
Preparing to replace initscripts 2.88dsf-13.4 (using
.../initscripts_2.88dsf-13.2_amd64.deb) ...
Unpacking replacement initscripts ...
dpkg: warning: unable to delete old directory '/run': Device or resource busy
Setting up initscripts (2.88dsf-13.2) ...
Installing new version of config file /etc/init.d/bootmisc.sh ...
Installing new version of config file /etc/init.d/checkfs.sh ...
[...]
Indeed, /run still exists.
Especially during this time of experimentation, it would be nice (but
certainly not required) if prerm + postrm made sure allow "upgrades"
back to the pre-/run state worked gracefully.

Given that /run is now mandatory and downgrades are not supported,
I'm not sure it's worth the effort. Also, this is a common problem
for all packages which try to remove a directory which is also a
mountpoint.
We can't remove the bindmount because it's only a bindmount
transiently until reboot, after which it's a tmpfs. And that tmpfs
is a protected mount, i.e. it's not umounted since it contains
critical stuff for e.g. networked filesystems so we can't umount it
since it could potentially break the operation of the rootfs.
Regards,
Roger
