linprocfs inside
Hi there
I'm currently playing again with Debian kFreeBSD based jails under a
FreeBSD Host. Because Debian mounts linprocfs on /proc and applications
like PostgreSQL does needs it, that brings me inside really ugly
situations. Here a short listening for example
freebsd-one# mount -t linprocfs linproc /tmp/test
freebsd-one# ls /tmp/test
0 12 15 1593 1598 1604 2506 3 3368 5 9 loadavg
partitions uptime
1 13 1589 1594 16 17
2509 3237 3369 6 cmdline meminfo scsi version
10 1316 1590 1595 1601 18
2510 3260 3370 7 cpuinfo mounts self
1074 1329 1591 1596 1602 19
2511 3365 3452 8 devices mtab stat
11 14
freebsd-one# mount -t linprocfs linproc /services/pgsql-one/proc/
freebsd-one# service jail start

In fact Debian has no real useful solution to bring Debian kFreeBSD on
physical servers. But for running Debian kFreeBSD inside masshosting
environment (what is a real attractive idea) like jail based VServers
thats will be the pain in the ass. I've noticed that some guys here are
porting jails to Debian kFreeBSD. I hope they will read this post and
thinking about it.
But PostgreSQL9 from backports on squeeze runs really nicely here.
