@mihail_karpych - in relation to your logrotate question, see my answer here: https://github.com/kaltura/server/issues/3872#issuecomment-187721179
@mihail_karpych - in relation to iOS playback, if you have an HLS delivery profile set up, it should work fine, see my comments here: https://forum.kaltura.org/t/how-to-configure-kaltura-11-7-0-for-hls-m3u8/4501/12
@verdonv1 - it should not be necessary to run that script anymore, everything is already done as part of the kaltura-base RPM's postinst phase
