With regards to said bug, gzip compression seems to work fine on RELENG_8, at least in my experiences: http://jdc.parodius.com/freebsd/pxeboot_serial_install_8.html I'm not sure the level of compression is what triggers the bug though; I haven't tested all levels (1 through 9). CC'ing jhb@ since he last updated PR kern/120127 (which I would say is still a problem on RELENG_7 :-) ). John, are you aware of any gzip decompression / mfsroot changes which might explain the problem on RELENG_7? I haven't done a "thorough" series of tests, but on my testbed boxes RELENG_8 works fine with a gzip'd mfsroot. -- | Jeremy Chadwick j...@parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
