will give you tmpfs instance on /mytmpfs which can allocate 10GB
RAM/SWAP in 10240 inodes and it is only accessible by root.
+tmpfs has the following mounting options for case-insesitive lookups support:

+========= ==============================================================
+casefold Enable casefold support at this mount point using the given
+ argument as enconding. Currently only utf8 encondings are supported.

+========= ==============================================================
+
+Note that this option doesn't enable casefold by default, one needs to set
default; one needs to set the
+casefold flag per directory, setting the +F attribute in an empty directory. New
+directories within a casefolded one will inherit the flag.
Thanks for the feedback Randy, all changes applied.
