Problem calling R from within perl script on Windows
I need to call R from within a Perl script. I do so using a system call like
this:
@args = ('R --vanilla --quiet --file=Rblock');
system(@args) == 0 or die "system @args failed: $!";
The script works perfectly when run in Mac OSX or Linux. In Windows XP it
fails with the message " 'R' is not recognized as an internal or external
command, operable program or batch file".
To ensure that R...

[GIT-PULL] XFS filesystem driver
This pull request contains the XFS filesystem driver for Syslinux.
Due to historical reasons (SGI IRIX's design of disk layouts), the first
sector in the primary AG on XFS filesystems contains the superblock,
which is a problem with BIOSes, since VBRs must be loaded up from the
first sector of the active partition.
Thus, we needed to handle this issue by putting the Syslinux
bootsector hard-coded in the 4th sector (at offset 2048) which is an
unused area in XFS filesystems. The MBR code will know how...
