Subject: Added OS check to mkrlconf.sh. Bypass checks for BIOS-mode boot
X-Git-Url: https://code.delx.au/refind/commitdiff_plain/d738a7a9d29a6a09673f1d9cad6155c07d0d3875

Added OS check to mkrlconf.sh. Bypass checks for BIOS-mode boot
loaders when run on a UEFI-based PC, since these checks are useful
only on Macs.

 0.8.8 (3/??/2015):
 ------------------
 
+- The mkrlconf.sh script now checks the OS on which it's running, which
+  should help avoid confusion or problems by users who mistakenly run it
+  under OS X.
+
+- rEFInd now skips checking for various BIOS-mode boot sector signatures
+  when running on a UEFI-based PC; these checks are run only on Macs. This
+  may reduce startup time on systems with many partitions.
+
 - Fixed Debian debinstall script to work correctly on IA32 systems. It had
   a bug that caused filesystem drivers and gptsync to not be packaged for
   IA32.
