New Revision: 276412
URL: https://svnweb.freebsd.org/changeset/base/276412
Log:
Fix loader's ability to read the 10.1 release PowerPC ISOs. There appears to
be some kind of problem with the version of makefs used for these disks.
There may be a better way to handle this problem, so I've set the MFC
timer for a fairly long time period.
MFC after: 2 weeks
