[solved][initscripts] cannot remove /var/lock

After upgrading to core/initscripts 2011.12.1-1 I have an error on boot: "rm: cannot remove /var/lock : Device or resource busy" - and the same error for /var/run.

I have:

$ df
Filesystem     1K-blocks      Used Available Use% Mounted on
rootfs         201585632  25129488 166216148  14% /

tmpfs              10240        52     10188   1% /var/run

Is it dangerous situation? Or - can I just ignore the errors?

Re: [solved][initscripts] cannot remove /var/lock

It's related to https://bugs.archlinux.org/task/18157

Just guessing, please disregard if it doesn't make sense:

[karol@black ~]$ ls -l /var/{lock,run}
lrwxrwxrwx 1 root root 9 12-16 14:57 /var/lock -> /run/lock
lrwxrwxrwx 1 root root 4 12-16 14:57 /var/run -> /run

[karol@black ~]$ df
Filesystem     1K-blocks     Used Available Use% Mounted on
rootfs           7566432  4153964   3028116  58% /
udev               10240        0     10240   0% /dev
/run               10240      172     10068   2% /run
/dev/sda3        7566432  4153964   3028116  58% /
shm               251324        0    251324   0% /dev/shm
tmpfs             251324       20    251304   1% /tmp
/dev/sda1         101105    17237     78647  18% /boot
/dev/sda4       30534108 22558556   6424480  78% /home

If /var/{lock,run} are symlinked to stuff in /run and /run is mounted as /run, maybe it doesn't like that you have /var/{lock,run} mounted as tmpfs.

@karol

I'm not sure to have sufficient experience to dig in the task as well into /usr/lib/initscripts/arch-tmpfiles file containing "comments explaining how the different entries work"

Re: [solved][initscripts] cannot remove /var/lock

I'm currently reading the bug report comments but no epiphany yet. I see you have a separate /var partition and it may be a factor too (I see it mentioned in the bug report).

Do you bind / mount /var/lock as tmpfs yourself? I'm not seeing this on my computer.

Re: [solved][initscripts] cannot remove /var/lock

Aha, it helped:

$ ls -als /var/{lock,run}
0 lrwxrwxrwx 1 root root 9 Dec 19 08:00 /var/lock -> /run/lock
0 lrwxrwxrwx 1 root root 4 Dec 19 08:00 /var/run -> /run

Thanks!
