https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D267628 --- Comment #5 from cgull@glup.org --- I have some WIP addressing this and adding enhancements, which I'd not fini= shed testing before the holidays. It may be a bit late now, but my fix to growfs is to check stdout/stderr for mountpoints in growfs.c instead. That's less general, but growfs() and /sbin/growfs aren't very general-purpose to begin with. I think kib's appr= oach is fine, though. I have some other minor changes to growfs to avoid writing to stdout/stderr unnecessarily, and I also implemented my proposed enhancements to growfs.c, growfs() syscall, and /dev/ufssuspend to write new cylinder groups before rewriting the last existing cylinder group. I'll finish testing these and make them available for review soon. --=20 You are receiving this mail because: You are the assignee for the bug.=
