https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D276174 --- Comment #2 from Bill Blake <billblake2018@gmail.com> --- These are the commands and the resulting script that is put at the start of each out.img file: > mkuzip -A zstd -o out.img in.img #!/bin/sh #Z4.0 Format (kldstat -qm g_uzip||kldload geom_uzip)>&-&&mount_cd9660 /dev/`mdconfig -af $0`.uzip $1 exit $? > mkuzip -A lzma -o out.img in.img #!/bin/sh #L3.0 n=3Duncompress m=3Dgeom_$n (kldstat -m $m 2>&-||kldload $m)>&-&&mount_cd9660 /dev/`mdconfig -af $0`.$n= $1 exit $? > mkuzip -A zlib -o out.img in.img #!/bin/sh #V2.0 Format (kldstat -qm g_uzip||kldload geom_uzip)>&-&&mount_cd9660 /dev/`mdconfig -af $0`.uzip $1 exit $? I can't speak to the kldstat/kldload stuff since I didn't actually run these scripts. However, look at the second example, which uses lzma. It tries to mount /dev/md*.uncompress. However, the mdconfig creates /dev/md*.uzip, so= the mount fails. (I did the commands manually to confirm that this sequence doe= sn't work.) The other two correctly use the .uzip device. But in all three cas= es, the mount is mount_cd9660, which won't work since the file systems actually created are ufs file systems. They need "mount -o ro" instead. (Again, manually confirmed.) Also, a nitpick: The mdconfig calls should have an option "-o ro". Where it matters is when the config'd image is on a read-only file system; mdconfig = will generate an error message without the read-only option, though it still con= figs the file. --=20 You are receiving this mail because: You are the assignee for the bug.=
