Hello,
I'm wondering how FreeBSD would behave if I did the following for eac
of about 400 directories (domains) per server:
cd /home/web/user_dom/
mkdir bin
mkdir sbin
mkdir etc
mkdir usr
mkdir temp
mount_null -o rdonly /bin bin
mount_null -o rdonly /sbin sbin
mount_null -o rdonly /etc etc
mount_null -o rdonly /usr usr
i.e. have about 1600 mount points on a single machine. The purpose of
the exercise is to create chroot() environments that get updated
automatically when the base system is updated...
#!/usr/bin/perl
$counter=0;
while($counter<500)
{
print counter;
$counter++;
system("mkdir $counter");
system("mkdir $counter/usr");
system("mkdir $counter/etc");
system("mkdir $counter/bin");
system("mkdir $counter/sbin");
system("mount_null -o rdonly /usr $counter/usr");
system("mount_null -o rdonly /sbin $counter/sbin");
system("mount_null -o rdonly /bin $counter/bin");
system("mount_null -o rdonly /etc $counter/etc");
}
will happily create a test environment, afterwards
$ mount
of course looks pretty crowded, but what other things do I need to
consider? Has any one got any experience with this kind of stuff?
TIA & best regards,
Gabriel
