Hi,
init_chroot appears to be broken when used with unionfs (it did work someti=
me=20
before RELENG_7 [definitely before the BETA's]). When using -current (with=
=20
the vaps patch :-) I get the following message before the system stops:
[...]
stat(c2d3fcc0,d3ceccfc,8,c0b094e7,c0bbc0a0,...) at stat+0x2f
syscall(d3cecd38) at syscall+0x2a3
Xint0x80_syscall() at Xint0x80_syscall+0x20
=2D-- syscall (188, FreeBSD ELF32, stat), eip =3D 0x826fe23, esp =3D 0x9bfb=
fe9bc,=20
ebp =3D 0xbfbee98
I tracked the stop to line 320 of init.c:=20
if (chdir(kenv_value) !=3D 0 || chroot(".") !=3D 0) =20
Also, I have a init_script that sets up a few things, here it is:
PATH=3D/rescue
trap 'echo Recovery console: ; PATH=3D/rescue /rescue/csh -i ; exit' 1 2 3 =
6 15
mount -t cd9660 -o ro /dev/$(mdconfig -a -t vnode -f /base.uzip).uzip /base
MD=3D$(mdconfig -a -t malloc -s 32M)
newfs /dev/$MD
mount /dev/$MD /tmpfs
mount -t unionfs -o noatime -o copymode=3Dtransparent /tmpfs /base
Note:
o) /base.uzip is a mkuzip image of an iso of the base system
o) If the sets after MD=3D... are skipped then the system mounts cleanly
If I can only get tmpfs to work then this can become a really flexible live=
=20
CD :-) .....
If you require any further information (or my build scripts) please let me=
=20
know
Regards
David
