sys-boot/systemrescuecd-x86-grub: Update for 6
SystemRescueCD starting from version 6 is based on Arch and the way it is booted changed. Rewrite to: - Support SystemRescueCD versions 5 and 6. - Create menu entries for all versions found. - Add option to copy the newest ISO to /boot if there is enough free space. Helpful if / becomes unaccessible while /boot is on a separate partition. - Add a menu entry for persistent boot (version 6 only). Will put data on the same disk, where the current ISO resides, in "/persistent_sysresccd-${version}/x86_64".

+# Here you can set custom bootoptions for the SystemRescueCD
+#
+# For SystemRescueCD version 6.x:
+#
+# You can add in a space separated list:
+# setkmap=xx: set keyboard layout for terminal
+# copytoram: load the ISO fully in memory
+# requires 2GB of memory to cache the system
+#
+# For SystemRescueCD version 5.x:
+#
+# You can add for example in a space separated list:
+# setkmap=xx: which defines the keymap to load (example: setkmap=de)
+# dostartx: load the X.Org graphical environment and launch Xfce
+# docache: causes the iso file to be fully loaded into memory
+# this requires 400MB of memory to cache everything
+# doload=xxx: loads needed kernel modules (example: doload=3c59x,e1000)
+# noload=xxx: prevents loading kernel modules
+# nomodeset: do not load the Kernel-Mode-Setting video driver
+#
+# Example:
+# SRCD_BOOTOPTIONS="setkmap=de docache dostartx"
+#
+# For all available bootoptions see:
+# http://www.sysresccd.org/Sysresccd-manual-en_Booting_the_CD-ROM

+# After changing this, you must update your grub configuration file, to take effect
