Subject: Makefile: allow tmpfs size to be more easily overridden, and use 500 MiB by default... 
X-Git-Url: https://git.rkrishnan.org/components/%22news.html/rgr-080307.php?a=commitdiff_plain;h=d6d759f590779e7b173d92e25c1dd988c8fe4f04;p=tahoe-lafs%2Ftahoe-lafs.git

Makefile: allow tmpfs size to be more easily overridden, and use 500 MiB by default (rebased).

(The kernel will only allocate space that is used; the limit is just in case
tests write more than expected.)
