[ug-bosug] Solaris Developer Express : Memory Requirements

[Moinak Ghosh]

Hi Bish,

   Very true, I understand your problem and the installer
should not make such big demands on memory when the
OS itself can happily chug along with 512MB RAM.

What I meant was it is possible for the SX Installer to make
do with much less RAM requirement by running binaries
directly off the CD like BeleniX. But this has not been done.
All the binaries are uncompressed in one huge ramdisk.
Even for a multi-cd install one huge ramdisk is not required
so I am not sure why CD-based execution was not done for
the SX installer.

Regards,
Moinak.
