#TODO check if _getCtimeMtime | sort removal needs to be backported
#TODO backport treeList sed -r sed -E 's/^.{10} +[0-9,]+ [0-9/]{10} [0-9:]{8} //' fix && _getFileCtimeMtime* IFS read fix
#TODO LANG=C... backport to v1.2.1 and v1.1
#TODO: conflict list is not mandatory, but is still needed for acl resolution
#TODO: syncAttrs must move the file list to sub function, which checks which kind of file list to use

###### Sync core functions
## Rsync does not like spaces in directory names, considering it as two different directories. Handling this schema by escaping space.
## It seems this only happens when trying to execute an rsync command through weval $rsyncCmd on a remote host.
## So I am using unescaped $INITIATOR_SYNC_DIR for local rsync calls and escaped $ESC_INITIATOR_SYNC_DIR for remote rsync calls like user@host:$ESC_INITIATOR_SYNC_DIR
## The same applies for target sync dir..............................................T.H.I.S..I.S..A..P.R.O.G.R.A.M.M.I.N.G..N.I.G.H.T.M.A.R.E
