You'll never silence the voice of the voiceless, Mel! Probably that was caused by overall instability of my 7.1 system: === # devfs -m /jailpath/dev rule apply path ttyp* unhide # chroot /jailpath/ # ls /dev dsp0.1 lpt0 mixer0 random ttyp1 ttyp3 ttyp5 zero log lpt0.ctl null ttyp0 ttyp2 ttyp4 urandom # script script: openpty: Resource temporarily unavailable # exit exit # devfs -m /jailpath/dev rule apply path pty* unhide # chroot /jailpath/ # script script: openpty: Permission denied # exit exit # devfs -m /jailpath/dev rule apply path * unhide devfs rule: unknown argument: Desktop # devfs -m /jailpath/dev rule apply type tty unhide # chroot /jailpath/ # script Script started, output file is typescript # exit Script done, output file is typescript # exit exit # === Now this seem to work, after the reboot. Although I'd like to ask if I used the major/minor numbers for temporary rules when portupgraded the 5/6 systems, what kind of rule I should specify to avoid 'openpty' reason of script(1) failure? Which tty devices does it use? You may see I try the path pty* and path ttyp* without that luck though. Major/minor numbers are gone since some of 6.X. 2009/01/25 17:08:14 -0900 Mel <fbsd.questions@rachie.is-a-geek.net> => To freebsd-questions@freebsd.org : M> On Sunday 25 January 2009 02:25:17 Peter Vereshagin wrote: M> > Hello, M> > M> > I am doing the portupgrade inside my jail.
