I have an odd issue, and I'm writing to see if anyone has seen the same
issue.
If I use "jexec 4 tcsh" or ssh into the jail, some sequences on the
command line kick me out (spontaneously exit) everytime.
For example, I run a couple of commands, then go to the /usr/local
folder, hit mv TAB (file name completion) realize I am in the wrong
folder, hit ^C, and the jail boots me. I've set the 'prompt' to be HOST
and GUEST for the main install and jail.

Here is a TRUSS on the last command:
truss jexec 4 tcsh
GUEST%mv write(17,"GUEST%mv ",9) = 9 (0x9)
read(16,0x7fffffffe0d2,1) ERR#4 'Interrupted system call'
SIGNAL 2 (SIGINT)
sigprocmask(SIG_SETMASK,{ SIGINT },0x0) = 0 (0x0)
process exit, rval = 1
Oddly, if I don't do a couple of seemingly arbitrary commands first (ls
and date in the example above), but go straight to the cd and then mv
command, the jail does exit with the ERR#4.
