[9fans] Fossil defaults (again)

[tlaronde@polynum.com]

Since I'm playing with the installation procedure (to be able to install
Plan9 without a CD reader; without pxe; without using GRUB+etherboot...:
done... Plan9 has everything once the FAT+PBS+9load interactions are
understood), I will have to modify several install scripts since, for
example, the scripts infer from the presence of a plan9:fat that
everything is OK---while I create a FAT from another system to be able
to bootstrap the install.

And since I'm reviewing things, two details :

1) In disk/prep/prep.c, the default minimal size for fossil is:

    {   "fossil",   200*MB, 0,  4,  },

With a distribution that is more than that, and the snapshot dance,
should this not be bumped?

2) Still in the same src, for swap:

    {   "swap",     100*MB, 512*MB, 1,  },

but pc/inst/fmtfossil sets from the definition of the swap the
value for fossil ncache. If the minimal default for swap will lead
to:

         m=256   # 2MB for fossil (this will be slow)

wouldn't it be better to increase the minimal size of swap?
