Title:
overlayfs alters /proc/self/exe link(s), making result a dead link.
Status in “linux-lowlatency” package in Ubuntu:
Confirmed
Bug description:
I've had this issue with other Ubuntu kernels.
Problem A:
This is not so much a bug in PulseAudio, but it is effected by this bug.
arcadia:~# invoke-rc.d pulseaudio start * Starting system PulseAudio Daemon
W: [pulseaudio] main.c: /proc/self/exe
does not point to /usr/bin/pulseaudio, cannot self execute. Are you playing
games?
invoke-rc.d: initscript pulseaudio, action "start" failed.
Details:
Looking at other process, like ntpd, it's clear something outside of PA is
not functional.
arcadia:~# ps $(pgrep ntpd)
PID TTY STAT TIME COMMAND
4595 ? Ss 0:00 /usr/sbin/ntpd -p /var/run/ntpd.pid -g -u 105:108
arcadia:~# ls -l /proc/4595/exe
lrwxrwxrwx 1 root root 0 May 31 13:53 /proc/4595/exe -> /sbin/ntpd <---
wow, that's wrong!
arcadia:~# ls /sbin/ntpd /usr/sbin/ntpd
ls: cannot access /sbin/ntpd: No such file or directory
/usr/sbin/ntpd
System settings:
arcadia:~# grep usr /etc/fstab
/dev/mapper/fsUsr.ro /.usr-ro squashfs defaults,ro 0 1
/dev/mapper/fsUsr.rw /.usr-rw ext4 defaults,discard,errors=remount-ro
0 1
none /usr overlayfs
defaults,lowerdir=/.usr-ro/local/..,upperdir=/.usr-rw/lost+found/.. 0 2
UUID=e7f6ec6c-631d-11e1-9522-9b80600299c1 /usr/local ext4 defaults,discard 0 2
I guess the contents of /.usr-rw and /.usr-ro may matter.
arcadia:~# ls -l /.usr-r?/*bin/{ntpd,pulseaudio}
-rw-r--r-- 1 root root 79260 Mar 8 21:36 /.usr-ro/bin/pulseaudio
-rwxr-xr-x 1 root root 601028 Mar 6 09:03 /.usr-ro/sbin/ntpd
-rwxr-xr-x 1 root root 79260 Apr 12 00:23 /.usr-rw/bin/pulseaudio
...I attempted to 'disable' PA by removing it's execute bits. I'm now
more fully making use of PA and life is better now.
