Hello all, To fix a bug in PF I recently updated my home firewall platform (a shrunk-down install of FreeBSD 6 on a CompactFlash card mounted read-only as /dev/ad0a) from the RELENG_6_2 to the RELENG_6 branch. All went very well there and the PF problem is resolved, but now I've run across a new issue.
Previously, when updating my CompactFlash image "in the field", I would boot the system into single-user mode via serial console, setup a small memory filesystem big enough to hold gzip, dd, and reboot (and their required libraries, with LD_LIBRARY_FLAGS set appropriately), copy the new flash image to the mfs, and run (from the MFS) "gzip -dc <flashimage | dd of=/dev/ad0 bs=8k" and then run "reboot -lnq" to reboot into the new image. This all worked well and good until the update to RELENG_6, and now I see the following when I try to dd the new image: # sysctl kern.geom.debugflags=16 kern.geom.debugflags: 0 -> 16 # gzip -dc <flashimage | dd of=/dev/ad0 bs=8k dd: /dev/ad0: Invalid argument 298+1 records in 298+0 records out 1220608 bytes transferred in 1.330433 secs (917452 bytes/sec) With the above kern.geom.debugflags sysctl, I thought I would have the ability to directly write to /dev/ad0 via dd, and this was the case with RELENG_6_2. Is this no longer the case? Didn't see anything in /usr/src/UPDATING to indicate any sort of change, and I'm not sure where in the RELENG_6 code this would exist (GEOM perhaps)? Anyone have any ideas or suggestions as to why this doesn't work anymore? Thanks! -Proto _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
