Looking at the name, i would have guessed, it is the > version of the freebsd userland, running in the jail. But it does't seem so. > j1 and j2 are VNET jails, so it seems the 1 in the vnet column signifies this, > j0 is a "standard" jail using the hosts network stack, so the 2 stands for standard? > Hi, osrelease is what the jail sees as kern.osrelease and uname -r (see: jail(8)) (i.e. kernel version); it's either specified during jail creation or inherited from the parent prison if none is specified. It looks like it's exporting a jailsys int for vnet, so these correspond to: JAIL_SYS_DISABLE=0 JAIL_SYS_NEW=1 JAIL_SYS_INHERIT=2 So 2 is 'use parent vnet', 1 is 'new one created' -- I don't see this described in either jls(1) or jail(8), it'd probably be nice if we translated jailsys ints into "new"/"inherit" since one specifies "new"/"inherit" for them during creation.
